Elliott Clark commented on HBASE-10129:
---------------------------------------
Most of this is already done in trunk (The most important HRegion have
metrics). I would be wary of this. The old 0.94 metrics system is pretty
prone to slow downs when adding metrics, and it looks like these will be hit a
lot. How much does this change the performance of HBase ?
> support real time rpc invoke latency percentile statistics for methods of

> It is important for applications to get latency statistics when invoking
> hbase apis. Currently, the average latency of methods in HRegionInterface
> will be computed in HBaseRpcMetrics. However, user might expect more detail
> latency statistics, such as 75% percentile latency, 95% percentile latency,
> etc. Therefore, will it be useful if we computing latency percentiles for rpc
> invoking of region server methods?
